The folks at Tips@mormontips.com are collecting stories that could help in their efforts to rid TSCC of its tax-exempt status. That might work for what you have in mind. At this point, I think the contributions are kept confidential.

Sorta related: About 40 ago, our local TV Channel XXX had a great segment where they would read letters from folks who got ripped off by some local business or another. Channel XXX quickly kiboshed that segment when those maligned businesses yanked their sponsorship.

Another station aired a great story about a guy in XXX local hospital who came out of a three-month coma just as his wife told doctors to pull the plug. In the interview, the man said, "I'll never go to XXX Hospital again!" That hospital yanked its advertising with that TV station.

I think what you're suggesting may be difficult if you are naming specific people or businesses. You never know how interrelated these entities can get. The guy who cheated on painting your house may have a brother who cuts your hair. You never know. Then, there's always libel!
